NO DOWNSIDES, I SAID!
There are better ways to achieve the same goal. Just publish the second-offset and make your adjustment explicitly when you have to. Then when someone comes along who has to maintain your system, they'll actually be able to tell.
As an aside, part of the leap-second resolution should involve finding the member of the POSIX committee responsible for that part of the POSIX spec and punching them in the forehead
Even if you only had service within city limits, you'd already be much more reliable than any cellular carrier I've ever tried. My android phone can run a SIP client and I've been kicking around the idea of just dropping the cellular contract and rolling my own solution with an asterisk server on a cloud service and a local wifi provider.
There will still be reporters and the news sites that managed to adapt enough to survive in the Internet era, but I don't think there will be print papers for that much longer. I suspect Google will be the largest employer of reporters in the future, and that they'll somehow figure out how to outsource local news reporting. Google had the kind of vision to build the media platform of the future. Newspapers didn't.
security guards and beat policemen do not carry guns

The guy (dead now) who shot up the Navy Yard had previously been in the military. And all he needed was a simple shotgun. The sort of thing that VP Biden says is exactly what people should own for hunting and self defense. He used that simple shotgun to shoot a military guard and gain access to that guard's handgun. He came across the rifle inside the Yard, said the Washington Post.
And no, just about nobody can buy an assault rifle. Do you mean a semi-auto rifle no different than every rancher uses to kill varmints in his cow pasture, only also equipped with black plastic parts that make no difference in lethality, but which make it look scarier to uninformed soccer moms?
